There are not a lot of modded WKs on here. I suspect that will eventually change. Maybe you can help lead the way. I lifted a 2002 Ford Explorer once and I had to get custom made coil spring spacers made to accomplish it. It should me much easier to lift a WK. I think it still has a solid axle in the back.

What you have planned sounds like a good start. Is the lift coil spring spacers or something else?
